摘要
针对引进De Nora公司的29DN350型离子膜电解槽出现电压升高的情况,从电解槽结构、操作条件、外部影响等方面分析,指出不使用极化装置是造成电解槽电压升高的根本原因。提出降低电压的措施有:重新设计29DN350型离子膜电解槽装置的极化电流;减少无计划开停车次数;尽快更换活性阴极;有效控制TOC。
By taking into consideration the phenomenon of the rising voltage of 29DN350 -type ion- exchange membrane electrolyzer introduced from De Nora co. , the electrolyzer struction, operation conditions and external influence are analyzed ,and it is found out that no using the polarization devices is the root cause. The measurents are proposed to decrease the voltage, that is, the polarization current of 29DN350 - type ion - exchange membrane electrolyzers is re - designed, the times of unplanned start - up and shut- down is reduced, the activated cathode is replaced as soon as possible, and the TOC is effecitively controlled.
